I. E. WINSOR METHOD OF AND APPARATUS FOR FUMPING WELLS Filed Dec. 51. 1926 ATTORNEY Patented Aug. 2, 19227u 'METHOD 0F AND APEARATUS FOR PUMPING WELLS.

Application filed December 31, 1926. Serial No. 1581353.

My invention relntei to u method of and apparatus for conducting u flow of fluid from wells und niore particularly to appurutus for Athe cniploynient of which the Well' casing may he utilized :is :i conduit for the overflow of the iiuid.

rlhe principal object of niy invention is to provide for the support of ii liner u ineens such :is zi well packer so positioned Within and ncur the lower end of u well cusing that the engagement of the pitcher with the Wells oi the cnsing will serve to divide und seal the well into upper und lower portions.

'By the use oli' niy device the fluid which is forced into the upper well portion through the liner suspended from the packer Will he prevented from escaping boch into the loottozn of the well, und the cosine,f of the seid upper portion will serve :is a conduit for the outl'iow of the fluid, thus eliniinuting the tubing reliiier such as is commonly .used in present practice A further` advantage of iny invention resides in the. suspension et the pumping, uppurutus from the lower end of the tubing in such manner that the saine can he removed 'from und replaced in positionin a, weil without disturbing the pocker.

Referring;` in detail to the drawings:

l designates .un oil Well provided with o lining casing 2 which extends downward from o, cuisiner hond 3 having un outlet flow line i und is supported on the cap rock 5 by the cusingjshee 6. The cap recite overlies the oil senil 7 und un oil pocket t3 within the sand contains oil which flows through thle sund into the pocket.

A `iluid pump indicated by the borrel l0 und the tubular pump rod il. oi the type iilustrnted in my op liontion for intent on oil Well puinp iiled ay M, 1925, erial No. 30,221, is sus `ended into the oil pocket 8 und iinmerset in the oil 9 for the purpose of forcing the fluid upward sind out through ilow line 4f which leads from the casing head upper end of the pump barrel 10 and en extcrnully threaded portion 13 of the head is adapted to engage within the internally threaded upper end 14 oit the barrel.

An opening l5 through the head l2 is pro vided for the reception of the pump rod 11 which is connected with the sucker rod 16 that extends to the top of the well and con stitutes the means o joining the pump rod to actuating means (not shown) at the mouth of the wel The ysaid pump rod ll reoipro cotes within the pump barrel 10 and causes the fluid to be lifted upward through the i channel 17 in the pump rod 11 and out of the check valve 18 into a pump support liner designated by 19, a portion of the fluid lomo in u manner shown as by screwthreeded engagementi, is a couplingr 20 having en opeuing 2l of slightly less diameter than 'the inm tei-nal diameter of the liner 19; the conical head l2 is positioned in seid opening 2l, the tapered portion ot seid conical head seating in :i tapered portion 22 of seid opening 2l oit coupling 20, the diocreluincy referred to in the relative diameters of interior ofthe liner l@ und the opening 21 of the coupling being provided for in order that the houd i2 will I have clearance when being puesed through the liner es will he described .A further feature of the internal outline of coupling 20 is the eylindricei portion 523 of the opening 2i extending downuurdly troni the tepore( portion und designed ior the reception of the pump borrel l() hy the couu pliug 20'.

The upper end ,of the liner 19 'is threaded into the lower end of n well packer 2li having jews 25 which engage the Walls of the casing 2 and .so enable the pitcher to support the liner i9 in u poeitiou neer the lower end of the casing, whereby that portion of the cesing;- above the packer is left open tothe flow et oil without other obstruction than the sucker rod i6. A screen 26 is provided dependingiirom the bnrrel sind attached thereto by e coder QT. The collar constitutes :i standing valve seat 'for the standing vulve 28 that has o beveled seat 29 for reception of the valve ball 30, the ball traveling in a sleeve 31 huw ing u cross iin 32 for limiting the trayel of the ball. T e sleeve has vertical ooves 33 on its inner Wall through which oilnmey pass lar 37, seat 38 and valve'ball 39.

,LiIil-n. annular chamber designated 40 of the barrel, pressed dowi'iward by the` cups 34: in 'the downward unctioningof the pump rod closes standing valve 28; and at the saine time, the pressure on the oil in said chamberI forces #said oil upward to open valve 36 in the lower end of the pump rod, the valve admitting thel oil, as the structure discloses, to the' interior of the tubular pump -rod 1l. The reversevor sucking action of Jthe pump withdraws .the oil in the lower part of chamber 40, theijeb withdrawino valve ballSO of standing vaive 28, the said Suction being'transmitted to the oil in the oil pocket yto draw thersame into the lower 'end of the barrel and of the valve, At the Wsame time, the upward motion of the pump rod results :in the seating ot the valve ball 39 of the valve 36 whereby the pumpvis enf abled to lift the oil contained within it upward in chamber of the barrel 10.

The pump rod' 11 is provided with ports 41 through which the oil, delivered as described vto the channel 17 in the pump rod, 'is deliv= ered from the pump rod 11 to the annular in a well are as follows:

The packer 24 with the liner 1 9 suspended' therefrom is lowered tothe desired'fposition in a well by such means as are commonly employed 'for that purpose and the packer is engaged with the walls of the casing 2- by the jaws 2b to hold the same securely in position,l and sealing that portion of the well casing above the packer from communicationv'with Athe 4ortioii below the packer.V

T- e pump bari-el 10 is then lowered into the well -suspended from the sucker rod 16I and passed through the packerl 211, the liner 19l and through the coupling 20, the passage J being facilitated by the fact above mentionedthat the upper interior diameter of the coupling is less than that 'ofthe-liner; until the, conical head 12 sea.tsjwithintlie tapered opening 22 of the couplingln opere ation reciprocating-motion is conferred on assignee the sucker rod 16 and the attached pump rod l1, and the luid is i'orced up through the barrel`10, as above described, into the liner 19. From the liner 1S) the fluid is forced upward through the'paclier 2e into the well casing above the packer, the well casing serving as a. conduit conducting-the luidto the casing head 3 iroiii which it passes oli through the ilow line Ll to storage tanks or the like (not shown).

What I claim and desire to secure .by Let- Acontrolling flow between the rod and liner, and means for operating the pump rod.

2. In combination with well casing,V a pump y'barrel suspended tromand having sealed relatioiivv'ithlthe cas-ing, an upwardly opening valve in the pump barrel, a hollow piston in theK barrel having an upwardly opening valve, a hollow rod Aon the piston having Avalved' communication with the casing, and means for reciprocating said rod.

3. n rombination with well casing7 a packer in said casing, a liner suspended from said packer, having communication with the 'casing and having a seat, a head in scaling relation with said seat, a pump barrel fsus- .pended from said seat, astundiiig -valve in tion with the linen' and means for operating l the rod.

4. ii combination with well casing, a

' 'packer in the casing, alhier suspqnd'edfrom said packer, communicating with the casing* above the packer andhaving a tapered seat, a conical head in upwardly removable sealing relation with said seat, a pump `barrelsuspended from said head, a hollow piston in, said barrel, having an upwardly opening I. valve, a hollow rod for saidpiston, slidable in said head and having an upwardly open` mg valve controlling communication between k the rod `and liner, and means itorreciprncatving said rod, said piston being engageable with said head upon extended upward movement' of the rod to lift the head from the seat.
